The couples were matched by Married at First Sight experts Pastor Calvin Roberson, Dr. Jessica Griffin, and Dr. Pepper Schwartz based on compatibility, personality, life goals, hobbies, religion, views of marriage and gender roles, and much more.
Over the course of the season, which filmed for seven weeks, each couple was shown navigating the joys and struggles of daily life together after agreeing to an arranged marriage.
Meanwhile, Stephanie explained while she felt confident AJ was invested in their marriage for the long haul, his frustrations tended to get the best of him at times and could be overwhelming.

"With 'Decision Day' so close, I worry about what troubles may come in the future five or 10 years from now," Stephanie told the cameras.
As for Jasmine and Will, she confessed they do not have a perfect marriage even thought she felt extremely comfortable and optimistic on their wedding day.
When Kate and Luke watched their video, it was a bit awkward because Kate was still feeling down from the events that had transpired the previous day.
Kate felt "attacked" by Luke when she was just trying to have a conversation about what she needed from him in order to make their marriage work long-term.
Kate felt pretty bad, but Luke's sense of humor eventually made Kate cheer up and laugh as they watched their wedding together.
Luke told Kate he was "happy," and the video brought back home happy memories for Kate as well.
"Marriage means a lot to me, and I just can't quit it because it's not going well. Like everybody says, marriage is hard... I just don't feel we've given it everything we could yet, and I want to keep going," Kate said in a confessional.
They both had a lot of thinking to do when trying to determine whether they were truly invested in the marriage and could eventually fall in love.
Eighteen hours before "Decision Day," each couple parted ways, as the rules required them to stay at different locations for the night.
The experts wanted each individual to spend some time alone in order to think things through and figure everything out.
Jasmine admitted she was "in limbo" in regards to her decision, and Luke found himself struggling to watch Kate walk away from their place together.
"We both care about each other a lot. It's been such a rough path, but we've grown together and it's definitely heavy -- super heavy -- thinking this might be the last time we're together in this apartment," Luke told the cameras.
Stephanie then acknowledged there was still a lot to learn about AJ, and Kristine was sad to watch Keith leave their place.
Ten hours before "Decision Day," every individual found him or herself alone. They had the biggest decision of their lives coming up.
Luke was stressed out because there was a lot of uncertainty, and Kate was sad and confused.
